Jack Nagel 7c648d9732 Shore up a number of shell quoting issues
When interpolating in strings passed to Formula#system, it should be
done in such a way that if any interpolated variables contain spaces,
they are either (a) passed as part of a list or (b) protected by quotes
if they are part of a long string (which is subject to shell expansion).
Otherwise, they will be split on the space when expanded by the shell
and passed as multiple arguments to whatever process is being executed.

# and installs the resulting binaries in a directory like:
# <nacl source>/build/<hostname>/lib/<arch>/libnacl.a
# <nacl source>/build/<hostname>/include/<arch>/crypto_box.h
# etc. Each of these is optimized for the specific hardware it's
# compiled on.
#
# It also builds both x86 and x86_64 copies if your compiler can
# handle it. Here we only install one copy, based on if you're a
# 64bit system or not. A --universal could come later though I guess.
